| ACTION | SINCE THE JOB WAS NOT PUMPED AS API CEMENT SLURRY AN NOAV WILL BE ISSUED TO REQUIRE A COMPRESSIVE STRENGTH REPORT FOR THE CEMENT MIXTURE PUMPED WITHOUT CEMENT ADDITIVES TO TIE IN THE EXCESSIVE WATER MIXED INTO THE SLURRY. ALSO IT IS POOR PRACTICE TO CEMENT WITHOUT THE FLUIDS RETURN BEING ESTABLISHED PRIOR TO PUMPING CEMENT. ESTABLISH GOOD CEMENTING PRACTICES ON FUTURE WELL REMEDIATION CEMENT WORK. CEMENT SPECIFICATIONS SHALL BE REQUIRED ON FUTURE CEMENT WORK. OPERATOR ADVISED ON SITE THE CEMENT DID NOT MEET THE INTENT OF NEAT CEMENT SLURRY AND PROCEEDED THE JOB WITHOUT FURTHER DISCUSSION STATING ALL THAT IS NEEDED IS COMPRESSIVE STRENGTH INFORMATION. |

OPERATOR PLANNED TO PUMP 500 SX TYPE 1/II CEMENT BASED ON WORK TICKET, WITH 2% CACL AND MIXED WITH 13.2 GAL WATER/ SX WITH TARGET WEIGHT OF 12.1 PPG. THE CEMENT JOB STARTED ABOUT 1:30 PM AND ENDED ABOUT 3PM WHEN THE BULK TRUCK BROKE DOWN. PREFLUSH WAS 10 BBL AND MIX WATER WAS 109 BBLS WITH ESTIMATED CEMENT ABOUT 400SX BASED UPON TAPPING THE BULK TANK. THE MIX VOLUMES DID NOT COMPUTE AND WATER VOLUME METER WAS INACCURATE ON THE BISON REMOTE COMPUTER. THERE WERE NO RETURNS TO SURFACE AT ANY TIME DURING THE CEMENT JOB. THEREFORE IT IS NOT DEFINITE WHERE THE CEMENT WENT WITHOUT BOND LOG VERIFICATION. THE BULK HOPPER BROKE DOWN AND THE JOB WAS CONSIDERED INCOMPLETE WITH NO (HEAVY) NEAT CEMENT PUMPED BEHIND CASING PER RECOMMENDATION OF INSPECTOR. CEMENT DISPLACED FROM TUBING WITH 20 BBL WATER AND ONE JOINT LAYED DOWN WITH EXCESS REVERSED TO PIT. WOC. WATER HAULER INDICATED ABOUT 160 BL WATER TOTAL CONSUMPTION DURING JOB. THIS WOULD WORK TO FURTHER DILUTE THE INTENDED SLURRY. DENSIOMETER RANGED 11.7 TO 12.2 DURING THE JOB. |
